Description
technical field [0001] The invention relates to the fields of experimental fluid mechanics and powder industry, in particular to a gas-solid two-phase flow state parameter detection device based on photometric changes and its application, which can reproduce actual working conditions. Background technique [0002] In the process industry, there is a wide range of technological processes and storage raw materials that use powder as the main working medium. Generally speaking, the conveying methods of powder can be mainly divided into mechanical type and pressure type; among them, the pressure type conveying method mainly uses compressed gas as power to make the powder fluidized and flow in the form of gas-solid two-phase flow in the special The transfer job is completed in the pipeline. Since the mechanical properties of gas-solid two-phase flow have always been difficult to quantitatively analyze, most of the relevant researches have simplified and reduced the experimental ...
